Description

The Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 4.16.18 via the allowed_mime_types function. This is due to the unconditional registration of an upload_mimes filter that adds executable file extensions (.exe, .apk, .msi) to the global WordPress MIME allowlist, without scoping the expansion to digital-product upload contexts. This makes it possible for authenticated attackers, with author-level access and above, to upload files that may be executable, which makes remote code execution possible. This filter is registered globally on every request regardless of whether the digital products feature is configured or in use, meaning the expanded MIME allowlist affects all WordPress upload contexts site-wide.
